Application medau ust 1?, 914. Serial No. 857,045.

To all 'whom it may concern: Be it known that I, Jnnrcrs H. 'SoHLArLY, a' citizen of the United. States, residing at Canton, in'the county of Stark and State of 5 Ohio,'have invented a new and useful Sheet- -Metal Structural Section, of ,whichthe followiiig' s a specification.

My invention relates to improvements in sheet metal structures and While applicable to structures for various purposes has special xtgference to the construction of sheet metal s ructural sections for silos and thefllike.

The objects of the invention are, to generally improve structures of the character mentioned, to provide a silo or the like which will be strong and durable and thoroughly air and water tight and thusadapted to thoroughly preserve and retain its contents, and to provide a knock-down or sectional construction wherein the various parts or :sections are so constructed as to be interchangeable; thus makingthe erection of the device an easy matter mthat said sections in'eednot be put together in any one, predetermined order or arrangement. and the cans, of connection for the varioussections ibe ingz-simply "and readily understoodby un-.

Additional objects'are the provision of air andwater-tightjoints between the various sections, the. strengthening'of the edges of the sections so asto brace the joints and the ,pr otection of ,the joints by integral-protect- "in flan es.

' eferring more especially to the-construction disclosed in the accompanying drawmgs each section 1 is substantially rectangular and is preferably arranged with its long dimension horizontally. Each section is the desired circumference of the silo desired to be constructed and two adjacent edges preferably the top and one side edge are provided with the plain out-turned integral flanges 2 and 3, respectively. The top flange 2 is provided with the beveled edge 4 at either extremity by neans of which theouter edge of the flange 2 isflo'f greater length than the inner '6 thereof, thereby forming overhanglng angular extensions 7 at either end of the flange 2, said extensions being adapted to overlap those-of the next adjacent sections when the sections are assembled 'as shown more'clearlyin'Fig. f the drawings. The opposite orbottom and other side edge are provided with the outturned flanges 8 and 9 respectivelyf said flanges 8 and 9 being integral auxiliary protecting flanges 10an'd"11 respectively, said flanges '10 and 11' extendingat right angles to the flanges 8 and '9 and lying in planes parallel with the body portionof the section. The filanges 2, 3,18. and 9'are allprovided with bolt-apertures 12 to receive bolts 13 for fas The lower flange fi'is provided with a beveled edge 14 of greater "length than the in'neredge 16'thereof. Overhanging-ang ular extensions 17 are thereby ormed at either end of'the flange 8, said ex.- tensions" being adapted] to overlap those of the next adjacent sections when the sections are assembled'asshown more clearly 3 of the-drawings. The upper and lower edges 18-"and; 19 respectively of the flange -9 andthe upper and lower edges 20 and 21 which, the

in Fig..

respectively of. th'e'flange 3 a're slightly bev- I .elefd as s'hownin-theidrawings. By this constructi'on the-flanges"? and 3 are-slightly 145 portant feature of against relative and it will be seen that, from an inspectionof this figure, sufficient space is left between the lower beveled edge 9 and the horizontal flange 8 to allow theflared extremities of the adjacent horizontal flanges to be inserted 16 therebetween.

By reference to Figs. 3 and 4 of the drawings it will be seen that in joining adjacent sections in any one tier the flange 9 is brought face to face with the flange 3 of an adjacent section 'the flange 11 formed integral with the flange 9 extendingover the edge of the flange 3 and thus protecting and covering the jomt.- Between the flanges'3 and v9 packing of any well known material may be arranged, if desired before drawing up the bolts 13, said packing helping to produce an airtight joint, although it is not 1 necessary to use the packing and in the accompanying drawing no packing is shown. Xv When each tier has been connected and arranged in place the top plain flange 2 of i the various sections constituting the tier will form an annular outward extending flange upon which the bottom flanges 8 of the sections of the superadjacent tier are adapted to rest. Here again packing may beemployed if desired in order to form a tight joint and bolts 13 may be used to fasten the flanges together. The protecting flanges 10 of the various sections extend over the flanges 2 as will be especially noted with reference to Figs. 3 and 4 to produce a dependent water drip adaptedv to carry any water over and beyond/the joint. im-

the construction is the strengthening and bracing. eflect produced by the flanges 10 and 11. By reference to Figs. 3 and 4 of the drawings it will be noted that when the outstanding flanges 2 and8 and 3 and -9 have been connected to form thehorizontal and vertical joints described, .said flanges serve to thoroughly brace and strengthen the wall of the silo so long as said flanges are maintained in' true. outstandingposition. The flanges 10, and- 11 act as braces for the said outstanding joint flanges, hold the outer edges of said flange's in true alinem'entoand thoroughly brace them against bending as well as movement which would weaken the-structure and loosen thejoints.

' The upper and lower flanges 2and' 8'iare outtvardlybeveled at their outwardextremities so that they will overlap the flangesof the adjacent sections upon either side'in the here the vertical edges of adjacent sections may be drawn tightly together and the flanges are held tightly together by means of the bolts thus producing an air tight joint ,even withoutthe use of packing material, it being only necessary to use one or two coats of paint upon the inside surface of the sections in order to produce an air tight silo. This is an. important feature in the building of silos as in cases where there are loose jomts in a silo and the outer air is so allowed to enter and come in contact with theensilage the entire contents of a silo is often ruined by fermentation.

Although the drawings and above specification disclose the best mode in which I. have. contemplatedlem'bodying my invention I desire to be not limited to the details of such disclosure, for, in the further practical application of myfi invention, many changes in form and construction may be made, as circumstances require or experience suggests, without departing from the spirit of the invention, within the scope of the appended claims.

1. In a silo, a plurality of sections; each section" comprising a rectangular sheet metal body portion provided at its'edges with outstanding flanges, the flanges of adjacent sections abutting each other, the outer edges of the vertical flanges of a section being shorter than the distance between its horizontal flanges, the outer.- edges of the horizontal flanges of a section being longer than the distance between its vertical flanges, whereby. the horizontal flanges of adjacent sections overlap each other at their ends.

2. In a silo, a plurality of sections, each section comprising a rectangular sheet metal body portion provided at its edges with vertical and horizontal, simple, outstanding flanges and compound flanges including outstandingportgons and auxiliary brace port ons lying in planes transverseto said outstanding portions, the outer edges of the. vertical flanges of a section beingshorter than the distance between its horizontal flanges, the outer edges of a horizontal section being'longerthan the distance between its vertical flanges, whereby thehorizontal flanges of the adjacent sections overlap each other at their ends, the simple, outstanding flanges of each section connected to the out-v standing portions of the'compound flanges of adjacent sections to form connecting seams and; said auxiliary portions extending over and protecting said seams and bracing said outstanding, simple flanges and outstandingportions against distortion.
